Iron in gas form?

I found a nice physics quiz the other day. My final score is ... none of your business. I thought we would finish out the week with some of the high points (which is to say: some of the low points).


28) Q: Iron can exist as a gas. True or false?

A:
(True.) Although iron is a solid at what we call normal temperatures, iron can also be a liquid, gas, or plasma. This is true of any element.


Plasma iron, then? Where do I sign up?
